Hello everybody:
I'd like to know if I can use the influence points on single-player mode. In particular, I would want to know the answer to the following question: When I get the influence points I have access to more powerful units, but can I use these new units in single-player or are they available in scenario editor?.
Also, could you tell me if the A.I is a good opponent to play against it on single-player?
Thank you so much.

Crowns aren't used in single player rmode, the AI is a decent opponent I've found. The online kingdoms and single player modes are completely seperate. The scenario editor is very powerful and worth taking a look at! You'll find all sorts of things in there
